Laptop: Dell Inspiron 15 3520

Window 11 Home rev.25H2

OS build: 26200.7171

Start11 does not work properly.

Left placed task bar is set to autohide. When taskbar is hidden, empty  area from taskbar(vertical band) is never used by the other apps, it is empty and I could not move manually any screen to use spare area. When window maximize button is pressed app does not occupy whole screen, up to the area where taskbar is appeared when unhide with mouse.

Time to time start button icon and search icon become invisible.

The same with another Dell laptop.

With Lenovo laptop window 11 it works perfectly. 

Let me know if more details are necessary.
